Abstract 摘 要:【目的】 调查PowerplexTM 16 System?STRtyper-10F/G kit以及AGCU 21+1三个分型体系包含的45 个常染色体STR 基因座在中国广东汉族人群中的群体遗传学数据,评估其法医学应用价值?【方法】 采集256例中国广东汉族二代家系(包含512名无关个体)外周血样,提取样本DNA,对D3S1358等45个STR基因座进行扩增,使用ABI 3500XL遗传分析仪电泳扩增产物,GeneMapper ID-X软件进行基因分型,并用相关统计软件计算常用法医学参数并进行Hardy-Weinberg平衡及基因座间连锁不平衡的检验? 【结果】 经Bonferroni 法校正后,45个STR基因座的基因型分布均符合Hardy-Weinberg平衡,不存在连锁不平衡现象?各基因座平均杂合度(Ho)为0.765,平均个体识别力(DP)为0.905,平均多态信息含量(PIC)为0.733?45个STR基因座的累积随机匹配概率(CMP)为9.48 × 10-50,二联体累积非父排除率(CPEduo)为0.999 999 999 94,三联体累积非父排除率(CPEtri)为0.999 999 999 999 999 990 4?【结论】 获得了广东汉族人群45个常染色体STR 基因座的群体资料,为广东汉族人群的法医个体识别和亲子鉴定提供了基础数据?联合应用PowerplexTM 16 System?STRtyper-10F/G kit和AGCU 21+1 系统可以满足突变?单亲?亲缘鉴定等疑难案件的需要?
